A roll and a method for producing a roll which are capable of effectively preventing tunneling are provided. A roll includes a core having a tubular shape and a laminate wound around the core. The laminate includes a process film, a surface coat layer, a substrate layer, an adhesive layer, and a release liner, in this order, in a laminating direction. The process film is formed from at least one member selected from polyethylene terephthalate (PET), polyolefins, and polyvinyl chloride (PVC). The surface coat layer is formed from a fluorine resin. The release liner is formed from polyethylene terephthalate (PET). The core is formed from an acrylonitrile-butadiene-styrene copolymer resin (ABS) or polypropylene (PP).

A winder includes a winding mechanism, a chamber housing the winding mechanism, at least one vacuum pump, and a product case. The winding mechanism is configured to wind a belt-shaped raw film around a winding core. The belt-shaped raw film is composed of a plurality of electrodes and a plurality of separating films. The at least one vacuum pump is configured to suck air into the chamber. The product case is configured to house a plurality of winding products each formed by winding the raw film with use of the winding mechanism disposed in the chamber.

The present invention relates to a material for packaging agricultural products, such as cotton, particularly in the form of cylindrical bales, by using automated agricultural machines and equipment of the self-powered baler type. More particularly, the present invention relates to a packaging material that comprises a single continuous film (1) composed of a plurality of packaging portions (2), which can be detached from one another via a break line (3), said packaging portion (2) being divided into an initial portion (2a) and a final portion (2b), and this latter portion is provided, on one of the surfaces thereof, with a layer of adhesive of non-permanent type 4. In parallel, the present invention also relates to a method for producing this agricultural product packaging material.
